Perhaps the best article on Advanced Reactors is the one from a US centrist group, third way. They describe Advanced Reactors as they existed at the end of 2015.

The first paragraph appears below, but the whole article is well worth reading.

Even the phrase “advanced nuclear” can be intimidating. But you don’t need a Ph.D. to understand the basic differences between the various advanced reactors under development in this burgeoning part of the clean energy sector. In this primer, we offer some background on the advanced reactor space and explain the differences between the nine different types of advanced reactors currently under development. We provide the basic information that policymakers need to understand the various coolants, fuels, reaction types, and sizes that could provide many paths to a single destination: clean, affordable, and reliable electricity.
